AI Technical Summary

Problems solved by technology

Additionally, the calibration of the glucose sensor may drift, resulting in a bias towards greater than true current blood glucose levels or less than true current blood glucose levels
Glucose sensors may also experience errors that cause the CGM to no longer respond to changes in true blood glucose levels and remain at incorrect artificially high or artificially low blood glucose readings
Finally, the glucose sensor may be in its infancy and have errors in blood glucose measurements until it stabilizes

Embodiment Construction

[0021] Embodiments described herein relate generally to methods and systems for determining basal infusion rate adjustments for insulin in a continuous glucose monitoring system for persons with diabetes, and in particular for use in determining basal infusion rate adjustments. Achieving at least one aggressiveness parameter when tuning. For purposes of defining this disclosure, a "measured glucose result" is the person's glucose level as measured by a glucose sensor; an "actual glucose level" or "true glucose measurement" is the person's actual glucose level.

[0022] refer to figure 1 , illustrates an exemplary continuous glucose monitoring (CGM) system 10 for monitoring glucose levels in a person with diabetes (PWD) 11 . In particular, the CGM system 10 operates to collect measured glucose values ​​at predetermined adjustable intervals, such as every minute, five minutes, or at other suitable intervals. The CGM system 10 illustratively includes a glucose sensor 16 having ...

Abstract

A method and a system of determining a basal rate adjustment of insulin in a continuous glucose monitoring system of a person with diabetes are provided. The method includes receiving, by at least onecomputing device, a signal representative of at least one glucose measurement; detecting, by the at least one computing device, a glucose state of the person based on the signal, the detected glucosestate including a glucose level of the person and a rate of change of the glucose level; determining, by the at least one computing device, a current risk metric, the current risk metric indicating arisk of at least one of a hypoglycemic condition and a hyperglycemic condition of the person; and calculating, by the at least one computing device, an adjustment to a basal rate of a therapy delivery device based on the current risk metric and a control-to-range algorithm comprising at least one aggressiveness parameter.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Utility Patent Application Serial No. 15 / 170,450, filed June 1, 2016, entitled "CONTROL-TO-RANGE AGGRESSIVENESS," which is incorporated by reference in its entirety This article. technical field [0003] The present invention relates generally to the processing of glucose data measured from persons with diabetes, and in particular for controlling the response to therapy based on a current risk measure and a control-to-range algorithm comprising at least one aggressiveness parameter Adjustment of the basal rate of the delivery device. Background technique [0004] By way of background, people suffer from type I or type II diabetes, in which sugar levels in the blood are not properly regulated by the body. Many of these individuals may use continuous glucose monitoring (CGM) to monitor their glucose levels on an ongoing basis. To perform CGM, a glucose sensor can be placed unde...
